I get brain fog, wake up feeling very blah and not refreshed. Unfortunately I have to have the Wifi router in my room. I ordered a EMF Wifi protector, a earthing pillow cover and a pair of CLIP-ON Anti-Blue Computer Glasses. Within a couple of days of using them, I noticed that my brain fog was gone and although I felt a bit tired waking up, it wasn't like a heavy feeling. Not sure if its a combination of all three, but I don't want to trial each one to see which is the one that is working as it's so nice waking up feeling good. As far as we know, it hasn't affected the Wifi signal, but the house is a small bungalow and the TV is no more than 10m away.
